             Summary: Support Read Only Kafka Topics / Clusters
                 Key: KAFKA-10187
                 URL: https://issues.apache.org/jira/browse/KAFKA-10187
             Project: Kafka
          Issue Type: New Feature
          Components: core
            Reporter: Manish Maheshwari


Request to support Read Only Kafka Topics / Read Only Kafka Clusters.

The reason so put a topic / cluster in read only mode is for deployments with load balanced multiple Kafka clusters where when a single cluster has to be taken out for maintenance, we want the ingest of new data into these topics / clusters to stop for some time. Consumption should still continue to allow consumers to catch up (including MM2 to replicate the data). With ingestion stopped we can be relatively certain that consumers will catch up in a controlled duration to then take the cluster out for maintenance.

Alternate workarounds exist by modifying LB configuration but they are not elegant and need a LB restart. We can also potentially enable firewalls on the host to block producer IP's but thats also not a clean solution.

Thoughts?
